Magnificent Coffee Machine Problem

Hello for a few days the coffee comes out watery, in the residues I no longer find the compact form but little coffee crumbled, I state that the grinding is set to the maximum fine grain equantita of coffee to the maximum, I regularly perform the descaling and cleaning of filter and dispenser, I also tried to do a reset of the machine but without results, can it be a problem of the board? Thank you

I have the same problem with a perfecta de longhi.I will take it apart sooner or later. It seems to me that a bit all models of this series have this problem.Tried changing gaskets,but nothing. Grinding finer or coarser is the same. Bho..... I will take it apart sooner or later. My guess is the grinder is starred, so as an ignorant person on the subject.

Francesco and Mattia, do you always have the same problem? What was the cause.
I'm in the same boat as you: watery coffee no longer like a short time ago.
Cleaning and maintenance of ruotine so I do not understand the problem.

I also have the same problem I changed the electronic board but did not solve it. I think it depends on the grinder
